Multifractal Solar EUV Intensity Fluctuations and their Implications for Coronal Heating Models
Ana Cristina Cadavid, Yeimy J. Rivera, John K. Lawrence +3
We investigate the scaling properties of the long-range temporal evolution and intermittency of SDO/AIA intensity observations in four solar environments: an active region core, a…
Heating Mechanisms for Intermittent Loops in Active Region Cores from AIA/SDO EUV Observations
A. C. Cadavid, J. K. Lawrence, D. J. Christian +2
We investigate intensity variations and energy deposition in five coronal loops in active region cores. These were selected for their strong variability in the AIA/SDO 94 Å intensi…
Observed Effect of Magnetic Fields on the Propagation of Magnetoacoustic Waves in the Lower Solar Atmosphere
J. K. Lawrence, A. C. Cadavid
We study Hinode/SOT-FG observations of intensity fluctuations in Ca II H-line and G-band image sequences and their relation to simultaneous and co-spatial magnetic field measuremen…
Rapid Fluctuations in the Lower Solar Atmosphere
J. K. Lawrence, A. C. Cadavid, D. J. Christian +2
The Rapid Oscillations in the Solar Atmosphere (ROSA) instrument reveals solar atmospheric fluctuations at high frequencies. Spectra of variations of the G-band intensity (IG) and…
Space-Time Distribution of G-Band and Ca II H-Line Intensity Oscillations in Hinode/SOT-FG Observations
J. K. Lawrence, A. C. Cadavid
We study the space-time distributions of intensity fluctuations in 2 - 3 hour sequences of multi-spectral, high-resolution, high-cadence broad-band filtergram images (BFI) made by…
Mesogranulation and Turbulence in Photospheric Flows
J. K. Lawrence, A. C. Cadavid, A. Ruzmaikin
Below the scale of supergranules we find that cellular flows are present in the solar photosphere at two distinct size scales, approximately 2 Mm and 4 Mm, with distinct characteri…
